SPECIFICATION forming part of Letters Patent No. '736,59 5, dated August18, 1903.

Applicatiou'iiled June 8,1901. Serial'No. 63,739. (No model.)

To @ZZ whom, it may concern-a Be it known that LJosEPH ARNOLD GROEBLI,

residing atV New York, in the county of NewV York and State of New York,have invented certain new and useful Improvements in Machines for MakingTrimmings, of which the following is a full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and use the same.

The present invention has for its object to provide an improvedapparatus or machine for the manufacture of a trimming which consists ofa strip of fabric folded longitudinally and having a characteristicdesign, as an undulated or fluted outline imparted toits folded edge,andwhich may have alsoa thread wound spirally around it, the spiralfollowing and conforming to the depressions along the edge.

.The apparatus preferably employed by me for manufacturing the articleembodies gen-- erally devices for folding the strip, means for formingor impressing the edge so that it will present the desired outline,means for feeding and ironing or pressing the trimming, and means forwinding the tread spirally therearound.

Hy invention consists, further, in certain mechanisms and appliances, aswill he hereinafter more fully described and the novel features pointedout in the claims at the end of this specification.

In the accompanying drawings, Figure 1 is a plan View of a machine formaking the trimming according to my invention. Fig. 2 is a longitudinalvertical section of the same. Fig. 3 is a sectional view of the folderand forming-disks on line A B, Fig. 1. Fig. l is a transverse sectiontaken on line C I), Fig. 1. Fig. 5 is a View, on an enlarged scale, of apiece of the finished trim ming.

Similar characters refer to similar parts throughout the several Views.

1 represents the base-plate of the machine, 2 an upright support whichhas bolted to it the angle-piece 3, to which is connected thefolding-guide f1, the shape of which is shown most clearly in Figs. 1and 3,1 wherein it is represented as having its sides turned over,

as at 5, in order to turn in the rawv edges of the strip of fabricpassed through it and toward the middle, as at 6, having bothits sidesturned in in order to give a second fold to the fabric in the centerthereof, all as will be well understood by any one skilled in the art.

I have shown a folder which givesadouble fold for the purpose of turningin the raw edges and then folding the fabric longitudinally along itscenter; but the preliminary folding of the edges can be dispensed with,if desired, and where in the claims I use the term folding-guide Iintend that term in its broadest acceptation.

Arm 7, projecting from the supportZ, fur- Vnishes an end bearing for theshaft 8, which is driven by worm-wheel 9 and Worm 10 from the maindriving-shaft 11, to which power may be supplied by a driving-pulley 12or by other suitable means and which is supported in bearings on thebase, as shown. carries a sleeve which provides a bearing for the otherend of the shaft 8. Carried on end of shaft 8 and revolving therewithare two guiding-disks 13 13 and the forming-disk 14, having itsperiphery shaped,as here shown, by alternate concave portions andcomparatively sharp elevated portions to present an outline which may betermed' scalloped or undulated. Key S passes through the disks 13 13 and14: and through clamping-collars on each side thereof to lock theseparts to shaft 8. In a sleeved bearing carried by an arm 15, projectingfrom the support 2 above arm 7, is supported the spindle 16 of a secondforming-disk 17, which spindle is free to revolve in said bearing. Disk17 has its periphery tinted or shaped with alternate con- Vexl portionsand comparatively narrow concave portions, so that it will mate or meshwith disk 14 and be driven by contact therewith. These two disks arelocated adjacent the end of the folding-guide and lie in averticalplane, which is a plane passing through the center of saidfolding-guide, and they are thus adapted to act upon the central foldededge of the strip of fabric issuing from said foldingguide. The circulardisks 13 13,

which lie close to the lower forming-disk 14:

Bracket 8".

on each side thereof, are of a diameter greater than the disk 14, sothat they are adapted to act as guides both for the fabric passingbetween the forming-disks and for the upper forming-disk to insure itsproper position with regard to disk 14. It is obvious that these disksmight be made stationary with the forming-disk rotating between insteadof having all the parts rotate together. These guiding-disks might bedispensed with altogether, and in their place stationary guideplatesmight be used to guide the fabric between the forming-disks and topreserve the position of said disks with relation to each other. It isnecessary in order that the folded fabric may pass between the upperforming-disk and guiding-disks that there be a free space between suchdisks. In the present embodiment of my invention, as shown mostclearlyin Figs. 3 and 4, I have provided for such free space by makingthe formingdisk 14 of greater thickness than the formingdisk 17, wherebyspace is left between the forming-disk 17 and the guidingdisks,whichwill allow the sides of the folded fabric to pass therebetween. It willbe obvious, however, that the same result could be accomplished if theforming-disks were made of equal thickness and the guiding-disksarranged in such a way as to provide for sufficient space on either oneor both sides of forming-disk 17. Rolls 18 and 19 are positioned to actas feeding-rolls for the fabric issuing from the forming-disks andlikewise act to iron or press such fabric. As most clearly seen in Fig.4, roll 19 is carried with the stud 20, which has a step bearing uponthe upright post 21. The stud 2O is driven to revolve this roll from theshaft 8 by a chain of gears 22, 23, and 24, meshing with the gear 25upon the stud itself. The bevel-gears 23 and spur-gear 24 are carried bythe stud 26, which passesthrough and has a bearing in the cross-piece 27of a U-shaped bracket rising from the base, the two legs of which areIindicated at 28 28. Collars are interposed between said cross-piece andthe respective gears. The roll is mounted on stud 29, which is carriedby arm 30, pivoted at 31 to post 32. The rod 33 has one end seated in alug carried by the bracket 34, (shown in Fig. 2,) bolted to the post 21.This rod 33 passes loosely through thel arm 30, and between a head 35 onsaid rod and the arm 30 a spiral spring 36 is seated, thereby holdingroll 18 normally in contact with roll 19. The pivoted arm and springholding it, however, allow this roll to be drawn away from its companionroll for insertion of material or at other times, as desired, andlikewise prevent injury to the material by furnishing a yielding bearingfor one of the rolls. As will be obvious, the head 35 might be made inthe form of an adjustable nut in order to adjust the position of thespring andthe amount of friction between the two rolls, of which roll 18is driven by frictional contact with roll 19, as will be rsa-ses clearlyunderstood and as is illustrated in connection with the same form ofdevice in a further part of this machine. These rolls may of course begeared together, so that both rotate positively. An angle-piece 37,carried by the post 21, supports a guide 38, which presents a narrowlongitudinal passage-way, through which the fabric passes after it hasissued from between the pressing and ironing rolls. The course of thefabric through the machine is clearly illustrated in Fig. 2, and it willbe .understood that the operative parts are alined, so as to be inposition to act upon such fabric or trimming as it passes in a straightline from one end of the machine to the other.

Next to the guide 38 is a device for winding a thread spirally about thetrimming, said device consisting of a tubular arbor 39, which has itsbearing insleeves 40 40, carried by supports 41 41 from the base. Thisarbor is driven by a gear 42 thereon and intei-mediate gear 43 from gear44 on the main driving-shaft. This device for winding the thread orrotary twister-head, as it iscom- Inonly called, comprises, further, adisk 45, which carries brackets 46, furnishing supports for thethread-spool 47, from which the thread passes through a guide-or eye 48in a lug on the back of the disk, through the cenr ter of the hollowarbor, through a second eye in the end of bracket 49, adjustablysupported upon the end of the arbor for purposes well known in the art,whence it is carried around the trimming as the twister-head is revolvedduring the passage of the trimming through lthe machine. A second pairof feeding and ironing rolls 50 51. receive the trimming as it issuesfrom the rotary twister-head and pass it on to any desired point. lowerroll 50 has its shaft 52 supported on an arm projecting from an upright53 and is driven from the main driving-shaft of the machine through worm54, worm-wheel 55 on shaft 56, gear 58, connecting gear 59v and gear 60on the end of shaft 52, as is clearly shown in Fig. 1. Roll 51 isrevolubly held by spindle 61, which spindle is carried in the end of thearm 62, pivoted at 63 to support 53, and is held yieldingly in contactwith the roll 50, from which it is driven by frictional contact orby-gears by means of the spiral spring 64, held between the nuts 65 uponthe rod 66 and the arm 62 in a like manner, as has been described inconnection with the adjustable roll 18 and as will be readily understoodfrom an inspection of Fig. 2.

In general the operation of my machine is clearfrom the foregoingdescription. A strip of fabric a is fed into the folder, which is shapedas shown, so that the raw edges are turned in, as shown at b, Figs. 3and 5, and the entire strip is further given a longitudinal fold alongits center. It then passes between the forming-disks, the upper one ofwhich passes down into the center of the fold on the inner side of theedge and the lower IOC Ifo 5 The TIOv

'leases of which coacts therewith on the outer side of the edge to shapethe fabric in conformity with the design which has been given to theperipheries of the forming-disks. This action is clearly shown in Fig.3, wherein the fabric is shown at o as having still astraight edge. At dthe operation is shown partially completed, and at e the trimming iscompleted so far as the characteristic design to be given to its edge isconcerned.

For the purposes of this specification it is immaterial whether it issaid that the fabric is bent, folded, impressed, or distorted into thedesired form. The function of the forming-disks is analogous to that ofroller-dies, and such function is clear whatever terms are to be appliedthereto.

While I have shown disks the peripheries of which are shaped so as togive the fabrica scalloped edge, it is clearly to be understood that theshape of these disks or rollers may be changed to give any desired shapeor configuration to the edge of the fabric. If desired, heat may beapplied to the formingdisks and pressing-rolls, whereby the pressing ofcertain materials will be facilitated and the appearance of the finishedarticle somewhatimproved, although this isin nowise necessary to thesuccessful working of the machine. Suchheatingmaybeaccomplished in anydesired manner, or any of the single parts may be heated without heatingall the others in a manner well known in the art.

The fabric passes from the forming-disks through the first pair offeeding and ironing rolls which have their axes perpendicular, so thatthe plane of the trimmingis not changed, then through the guide 3S andthe rotary twister-head, by the revolution of which as the trim ming ispassing through a thread will be wound spirally around the trimming,following and conforming to the depressions in the edge thereof, asclearly shown in Figs. 2 and 5. The proper ratio between the feedingmovement of the trimming and the rotation of the twister-head in `orderthat the thread may be wound -properly to conform to the outline of thetrimming is obtained by proper proportioning and adjusting of the gear43. Issuing from the twister-head the trimming passes between the secondset of feeding and ironing rolls 50 5l.

I have illustrated what I consider the preferable form of my invention;but I do not desire to be strictly limited thereto, as various changesin details may be made without departing from the spirit of myinvention.
